Functions

Features       

          Realizes long-distance monitoring of local device to the remote device based on self-copyright IC;

          Provides two clock types: E1 master clock, E1 line clock;

          Support SNMP for option

          Realize the automatically rate set of local device to remote device

          has the function of pseudo-random code testing, convenient for opening of the circuit, and can be used as an error code instrument;

          E1 supports 75Ω unbalanced and 120Ω balanced impedance at the same time;
